Patent CA-2217535-A1 (CA)
Inventor: SNYDER EDWARD A
IPC: B23K20/12
Filed: 1991-12-18
Abstract: An electromagnetically actuated friction welder produces orbital motion at interfaces between parts (usually of thermoplastic material) to bond the parts by fusion generated by friction.  This welder can also be operated alternatively to produce reciprocating vibratory forces thereby providing flexibility as to the selection of an orbital or reciprocating mode, depending upon the joint to be welded.  The velocity of motion is controllable preferably around the resonant frequency of the driven structure by adjusting the frequency of the AC power which operates the electromagnetic drive motor of the welder.  A plate which carries one of the parts to be welded and which is driven is flexurally mounted for movement in an orbital plane or planes containing the interfaces without substantial tilting by an array of stiff members, such as rods, located around the drive motor, attached to the plate at one end and to a tubular structure at the opposite ends thereof.  The tubular structure is desirably attached to a massive support carried by the frame of the welder.

Title: A method and apparatus for electrostatic separation
Inventor: WHITLOCK DAVID R
IPC: B03C7/02
Filed: 1996-04-25
Abstract: A belt-type counter-current separator for separating a mixture of particles, including conductive particles, includes a voltage gradient assembly having a plurality of conductive elements inter-disposed with a plurality of dielectric elements. The plurality of conductive elements are coupled to respective nodes of a voltage dividing circuit for dividing a voltage between a high potential electrode, of the electrostatic separator, and a reference potential. The plurality of conductive elements and dielectric elements in combination with the voltage dividing circuit limit a voltage potential between any adjacent conductive elements to a maximum potential so as to prevent sparking due the presence of conductive particles in the separator. In one embodiment of the separator, the voltage gradient assembly is an extruded plastic material having both conductive and non-conductive elements and pieces of alumina are disposed between the conductive elements to provide a durable voltage gradient surface.

Title: Method of adaptively adjusting the coefficients of a digital filter in an echo canceller
Inventor: MATT HANS JUERGEN
IPC: H04M9/08
Filed: 1997-11-13
Abstract: Digital filters are used to compensate for echoes in a transmission system in which unwanted couplings occur between a signal value in the receiving direction and a signal value in the transmitting direction.  The correct adjustment of the filter coefficients has a considerable influence on the achievable echo compensation.  Disturbance signals such as background noises, nonlinear effects in A/D converters or an active local speaker can briefly change the adjustment of the filter coefficients in a way so that the digital filter does not compensate for the echoes and causes additional echoes in unfavorable cases.  In accordance with the invention a set of filter coefficients (C(j)) are weighted with an envelope curve (H(j)) and an error measurement (F(j)) is determined therefrom.  Depending on the magnitude of the error measurement (F(j)), the filter coefficients (ci) are used for further processing or are discarded.  The pertinent arrangement comprises a first digital filter (1) for which the filter coefficients (ci) are continuously calculated in accordance with the NLMS algorithm.  These filter coefficients (ci) are stored, weighted and the best values are used to adjust a second digital filter (7) whose output signal (9) is subtracted from the echo-affected signal, creating an echo-free output signal (10) and thus significantly increasing the quality of a natural and undisturbed transmission, even with short-time disturbances.

Abstract: Method for making contact with a multipole female strip connector The present invention relates to a method for making contact with a multipole female strip connector for plug connections with coaxial connecting cables.      In order to simplify the method and to save tools, a multi-row female strip connector is split into plastic disks, one side of the disk having insulation-piercing terminals which are arranged one behind the other and are connected to contact springs, and the other side having correspondingly formed, overmolded pressure pieces. The disks are held spaced apart in a pressing tool by means of corresponding press-in pins which have a force fit. Coaxial connecting cables, which are cut to length and at whose free ends the outer insulation and the shield mesh have been removed over a predetermined length, are pushed into these disks, which are preassembled spaced apart. When the disks are pressed together, the pressure pieces press the connecting wires into the insulation-piercing terminal.

Title: Combine harvester rotor speed control and control method
Inventor: ARNER ROBERT J
IPC: A01F12/56
Filed: 1998-09-15
Abstract: The combine harvester has a threshing and separating rotor with a threshing cylinder section that cooperates with a concave to thresh crop material. A hydraulic motor drives the rotor. A hydraulic pump, driven by an internal combustion engine, supplies hydraulic fluid to tile hydraulic motor to drive the rotor. An electronic controller receives a rotor speed measurement from a speed sensor and compares the rotor speed with a selected threshing and separating rotor speed selected by an operator of the harvester and stored in the electronic controller. When the rotor speed varies from the selected rotor speed, the electronic controller sends a signal to a displacement control to change the threshing and separating rotor speed to approach the selected rotor speed. The displacement control can reverse the flow of hydraulic fluid to the hydraulic motor to reverse the direction of rotor rotation.

Title: Forward link carrier recovery in an ocdma spread spectrum communication system without a pilot tone
Inventor: OHLSON JOHN
IPC: H04B1/707
Filed: 1997-03-24
Abstract: A spread spectrum CDMA communication system in which a base station communicates with a plurality of subscriber terminals and the base signal transmitted by the base station is comprised of a set of substantially orthogonal functions which are overlaid with a pseudo-noise (PN) sequence forming a coded spreading sequence for an information signal, each orthogonal function of the set carries data for a single user in the system. Information signals are modulated onto the carrier to form a transmit signal and the coded spreading sequence on the transmit signal for broadcasting, each subscriber terminal having a receiver (41, 50) for coherently demodulating the base station signal. A plurality of correlators (53), each respectively tuned to different functions of the orthogonal signal set, are each followed by an appropriate nonlinearity (55-60) for removing the data modulation. The summed output of the correlators is used to improve the estimate of carrier phase over that obtained with a single correlator.
